To all whom it may concern:

Be it known that I, Joan B. BARTHOLO- MEW: a citizen of the UnitedStates, residing at Peoria, in the county of Peoria and 5. Stateoflllinois, have invented certain new .nnd useful Improvements inGang-Flows, .of which the following is o specification, reference beinghad therein to the nceompnnying drawing. 10

The main frame of the-plowlis a rigid structure made up preferablyOfstanda-rd structural steel shapes, and, as shown, consists of anobliquelynrrangd imgle betor beanrl, a front transverse angle but 2, aside. angle bar 3, on obli' n'ely dis os'ed' front bin {1 connectingthe. le t end 0 the front bar 2 and the front end of the side bar 3, andcentral s ngle bars 5, 5 connected-at their rear end to the beam l nndextending-forward bey0nd the "front hn-r Z-"These two bars 5, 5 areconnected by a' flat platefi and Patented Feb. 26, 1918..

The main frame is mounted on :four

' ground-wheels. JIhe' frontwheels 1:1,'11-a re' mountedbn aswinging'axle 12. ,This axle ca rrios a sleeve 13 lmvmg'an upright twonice 14 which fits-in a bearing aperture in u hearing block 15 secured.to the-front .end of the ireme horse, 5 The-lower side of the sleeve-'13has a dc nding trunnion 1 which iscngn gcd .hyfii rabe'ba'r 17 securedat its ro 'ur' cndlto the main frame and an porter} at its front by abolt 18. This bolt extends u ward through an aperture in the front on ofthe plate 6 and between the said plate and the nut 19 of the bolt isarranged a spring 20 which has the effect of drawing the brace bar 17upward against the sleeve 13 and at the same time permitting a certainfreedom of movement of the swingin axle. A curved draft bar 21 iscarried y the sleeve 13 and draft chains 22, 22 are connected to thedraft bar by triangular plates 23, as shown. 24 designates the rear endof the frame of a traction ongine and to this frame'the chains 22 areconnected. It is clear that as the traction engine is turned to one sideor the other the axle carrying the wheels 11 will be correspondinglyswung to guide the plow frame.

The rear part of the plow frame is supported upon wheels 25, 26. Thewheel 18 mounted on a shaft 27 which is carried y bearings 28 and 29 onthe main frame. The

wheel 26 is mounted upon a shaft 30. The

left end of this shaft is supported in a hearing 31 which is secured toand serves to rigidly connect the frame bars 7 and 8, the bar 8 beingdisposed in. a lower plane than the bar 7 to permit it to pass under theliftin cam of one of the plows. The right end o the shaft 80 is mountedin a beam ing 32 carried by one of the coupling brackets on the beam 1.The wheel 27 is disposed so that it rises between the two beam bars ofone of "the plows.

.Each of the individual plows has a beam consisting of two parallel bars33 and 34. The standard 35 of the plow body 36 is bolted to the rearends of the beam bars, and the front ends of said bars are spread apartto provide for a wide pivotal connection with the main frame. Thisconnection is effected by means of a pivot pin 87 carried by brackets orarms 38, 38 on the main frame. These brackets are preferably bolted orriveted to plates 39 which. are in turn rigidly secured to the beam 1.Each bracketis in the form of an angle bar 38 having two circularapertures, one near its front end .and the other near its rear end. Inthese apertures are mounted bearing blocks 40, 40. Each of these bearingblocks has a toothed flange 40" and an eccentric bearing aperture 40 toreceive the pivot pin 37. 41, 41 are toothed clips arranged to engageand lock the hear ing blocks 40 in.position, said clips being held inposition by bolts 42, 42 which pass through slots 43, 43 in the bracket38. It

I will be seen that the bearing aperture 40 can be adjusted forward orbackward or up and down by disengaging the locking clip 41 and turningthe bearing block.

By referring-to Fig. 1 it will be seen that the pivot pin 37 of eachplow is supported at its right end in the rear bearing of one bracketand at its left end in the front bearing of the next bracket. With thepivot i tive to the beam. A spring nected by links 49 with the standard.45.

Another arm of the lever 17 carries an adustable contact screw 50 whichis arranged to engage one of the beam bars and limit the upward movementof the wheel 44 rela' 51 interposed between the lever 47 and the plowbeam tends to draw the gage wheel 44 upward. 52 is a scraper carried bythe standard 45 in position to free the wheel. of soil which would tendto accumulate upon it. The le ver 47 carries an arm 47 by means of whichthe lever can be swung to force the wheel 4.4 downward or rather tocause the lifting of the beam relative to the Wheel. To effect such a.lifting of the beam I provide power mechanism adapted to swing thelevers 47 one after'the other so that the plows will be lifted insuccession.

A shaft 53 is arranged obliquely on the main frame adjacent the beam 1and on the shaft is mounted a series of segmental cams 54, one cam beingdisposed adjacent the front end of each plow beam. The shaft is mountedin bearings carried by a seriesof brackets 55 on the beam 1. thesebrackets being 'arran ed in pairs with one bracket on either si e ofeach of the cams. Each of the cams 54 has an outward and. rearwardcurved lifting part 54 and a circular or cylindrical part 54", and thecams are dislaced from-each other angularly as shown 1n Fig. 7. A leverarm-56, preferably in the form of two bars is pivotally connected totheupper end of each pair of brackets 55 and carries a roller 57 adaptedto ride upon I at the front end of the beam is of considerableimportance. Theoretically the location should e such that the chain 58extending forward from the lever arm 47 would pass through thehorizontal, axis on which the plow beam is pivoted to the main frame.This result i closely approximated by the v y P6; as this. makes itpossible to bring the constrnetion shown in Fig. 3 where the idler 59 ismounted upon'the pivot pin 37. Forprecticel reasons, however, I preferto mount the idler on the transverse rod 60 to-the rear of the pivot pin37, as shown in Figs. 1 and pivotal connection closer to the beam 1 ofthe main frame, and does not-materially interfere with thesecuring ofthe desired result, namely, the freedom of the plow to rise andfellwithontfinterference from the chain mechanism. The rod 60, as shownin Fig. 1, serves not only to support the idler 59 but 1150 braces thefront end of the beam bars. I prefer, also to provide an additionalbrace rod 61 at this point.

It will now be assumed that the rotation of the shaft 53 will cause thearms-54 to successively lift the levers "56, beginning at the rightsideof the machine, and cause, therefore, a successive lifting of theplows from theground, for it isobvi'bus that the 'rel'sltiveto'thebeam'snnd; therefor-dine liftmovement of the levers 56 is trnnsrnittedbythe chains- 58 to the levers 4;? causing the front'ends of said leversto swing downward ing of the beams relative to the ground W e s The: anme t of f am 54 on the'shaft 53 is such that ahalf revolution of theshaft will cause thelliftingof all the plows; and if then the shaft isgiven a further hnlf revolution the ploivs will be lowered in sncccss1onin the .same order in whichtheyfwere lifted.

To connect the sleeve 67 with the shaft 64 I provide a clutchmechanism which is adapted to be menuelly'engaged 'to cause theoperation of the plow lifti'n device'and to H t e-automaticallydisengage when the plows have been lifted-or lowered.

On the right end of the sleeve 67 isa. notched or serrated disk 77 andadjacent this disk and keyed to the shaft .64 is a larger circular disk78 formed at one point in its periphery with. a rounded notch 78. A dog79 is pivotelly mounted on the disk 78. The head of the dogca'rries'e-leterally extending roller 80 arranged to engiige with thenotch-ed periphery of the disk 77 and a spring 81', which-is interposedbetween the hub of the disk 78 and the dog 79, 'te'nds to press theroller 80 into engagement with the disk 77. A lever 82 is'pi'votallymounted on the bearing bracket (idbeneath thed-isk "T8 ancestries aroller 83Yadapted to ride upon the periphery of said disk. The leveralso carries a roller 84: which is disposed in the plane of the dog 79.85 is a coil spring interposed between the-end of the lever 82 end anextension-"66 of the bearingbrecket' G6 nnd'tends to pressthe roller 83radiallyinward against. the disk-78;. T-heupper end of the'lever 82hasconnecte'd toitai rope 0r cord 86 which-.extends'forwerd' to someconvenient point on the engine-pletform where it can be grasped i thedriver of the engine.

when the roller 83 lies within the notch 7 8 in the disk 78, the roller84 is. in position to engage the rounded back or tail of the dog .79andjswing the dog on its ivot. s'o-that the roller '80 is withdrawn romengagement with the continuously "rotetin'ghc utch disk '77. vfn'oW-tl'i'e driver IUl'lS'jO It downward and the spring 81' will expanand .cimse thedog 7910 swing 'the: arm 80 into engagement with'thefo'thting-disk :77

Thus by a simple pull upon the cord 86 the rotation of the shaft 64 isstarted and at the end of a single revolution automatically stopped. Asthe pitch diameter of the pmion 63 is half that of the gear 62 thesingle revolution of the shaft 64 thus produced causes a half revolutionof the cam shaft 53. As previously explained, a half revolution of thecam shaft causes the successive lifting of the several plows, and afurther half revolution of said shaft effects the successive lowering ofthe plows. It follows, therefore, that it only. necessary to give asingle pull upon the rope 86 to cause the successive lifting of theplows and that a secondpull of the rope is all that is required tocaiise the plows to be again lowered.

, When the plows have be n lifted for transportation from one place toanother it is desirable to relieve the cam lifting mechanism of thestresses to which they would be subjected in holding the plows up andfor this purpose I provide each plow beam. with a hook 87 which can beswung over the top of the standard 45. This serves to lock the beam tothe standard and relieves all the other parts of the lifting mechanism.

The operation of my improved gang plow will now bereadily understood. Onentering the fieldwhere the machine is to be used, if the plows havebeen locked up by means of the hooks 87, the latter are first disengagedand then with the machine at the starting point the driver pulls uponthe rope 86 which causes the engagement of the clutch mechanism. Thisresults in a half revolution of the cam shaft 53 causingthe plows to belowered one after the other, so that they all enter the ground onsubstantiall the same transverse line. At the end of t is halfrevolution of the cam shaft 53 the clutch is automatically disengaged,as

. previously explained.

' engage and produce a further When the turning point is reached thedriver has only to again pull upon the rope 86 to cause the clutchmechanism. to again half revolution of the cam shaft 53. Duringthissecond half revolution of the cam shaft the 0perative, or liftingflparts of the cams come into operation to e ect the successive'liftingof the plows, beginning with the one on the right, and thus the plowsare all lifted from the ground on substantially the same transverseline. After turning the plows are again lowered in the manner explained.

In passing over uneven or rolling ground the several plows are entirelyfree to rise and fall and maintain their uniform depth as determined bythe gage wheels because of the peculiar arrangement of the liftingconnections between the clutch chains 58.- As previously explained, eachof the lifting chains in pawing down under the idler 59 is caused toextend to, or approximately to, the axis around which the plow beamrises and falls. Obviously this feature of mimproved construction is ofadvantage urthermor when the plows are lifted and the machine is to betransported from place to lace.

The line of raft upon any one of the individual plows can at the sametime be raised or lowered within certain limits by adjust ing theeccentric pivot pin bearings in'the manner previously described.Furthermore by suitably adjusting said bearings the individual plows canbe leveled, and can be swung laterally, as will be readily understood.

The depth of the plowing can at any time be readily changed b simplyadjusting the hand screws 50 whic determine the work ing positions ofthe gage wheels relative to the beams.

I have shown in the drawings driving mechanism and both of the shafts 27and 30, but it should be understood that :{ie only of the ground wheelsmay be relic ,upon to drive Where power the plow lifting mechanism, istaken from both of the ground wheels it is desirable to use the pawl andratchet connections so that in turning the machine the wheel on theinside will not interfere with and cause slippage of the outside wheel.

I have above described somewhatin de' tail the parts of the mechanismshown in the drawings, but I wish it to be understood that I do notlimit myself to such specific details either as concerns matters ofconstruction or features of relative arrangement, as there can bemodifications without departing from the essential features of. theinvention.

It will be seen that an apparatus embodying all of my improvements maybe re arded as comprising a main draft frame %generally arrangedintermediate of a power tractor and the plowing devices, proper) thisframe being mounted in such way that it constantly holds the pointswhere the plows are attached in substantially the same relations to theound surface, this being in contradistinction frdm the earlier gan plowstructures which embody a do lex- [in system, or its equivalent, betweent e draft frame and'the series of plow bodies, such system having, foreach plow, two or more hinging lines or flexing lines, so that the frontend. of the beam, as-well as its rear end, was permitted to rise, orfall, more or les at the times when the plow bodies were raised orlowered.

It will be further seen that each of the plow units has (let) the plowbody which 15 held so as to vibrate vertically in fixed ingline withoutniaterially hifecting the 'l'tlativepositions of the body and thebody ithe main frame, (2nd) a beam which car-- arcs i relation to the lineofconnection to ries the body and is hinged to the frame,

ofthe beam are su ,portedand by which thegbody. can also; he lifted,and, (4th) a power transmitter ,oarriedby the beam and ,mou-ntedthereonin'suchway that the beam can fall below or rise above its normal work,

pp v I prefer to employ, in combination with the devices. justspecified, the others that have been above described; such as the depthadjuster, the stopping devicenvhich prevents the wheel or ground supportfrom rising beyond a; predetermined limit-relatively to the Ody, butwhich, at the same time, permits the power mechanism to, at any instant,move the wheel relatively downward. This isin contradistinction fromthose construetions in which there is a two-way lock interposed between,the wheel or ground support and the beam andpreventing any motion ofthe. wheel in either direction until the lock is open. I also prefer-docombine with the partsare in motion, "Its action is the opother parts aspring such as that described, a't' 5'1 which tends to move the wheeland the low body1apart;-permitting the body to qui c 1y sinktoitspredeter nined de 1 th in the earth aftenit has been. lowered reina suspended ,pos'ition., This spring acts to hold the parts together andprevent their separntii n,by jol'ting or jarring when the posite'of theaction of the springs that-have heretofore been used or proposed for usebetween leversand plow beamsand arranged totdraw. the leversforward andforce the wh el d w w r i t The power-transmitter- -(consistihg ot the Vdevices here..-select ed 'as typica1, thechain relation to thebody "and:the wheel, or

That-isto say,the" beam, to'getherlwith: the -Wheel and the plow body, cangfollowthe'. surface of the ground upwardmrdofwnward or along the normalhorizontalr planes; without variations in the distance beti n" thewheel"and the body, and 'c'on'sequ'en ris'inactivewhile it is "so working..Thi as; incontrastj -with earlier constructions which the chain, link,rod, cable, or equivalent for exerting tension or transmitting powertothe parts on the rear end-of the bfie'n extend directly backward" orupward from' power devices on the main frame to; "the mov ng devices on.the beam.

the latter will maintain 1ts-.- jpredet;erm d depth 10f work. The powertransmi ln those mechanisms the departures of the. beam and itsattachments from the predeter mined normal plane of action wereimmediately followedby variations inthe relative positions of the wheeland the-plow body. That is to say, the power devices or the powertransmitter was constantly liable to exert pressure on the ground wheeland. lift upward the body somewhat, thus causing shallower plowing. Byarranging :the power transmitting parts in such Way that one of theprincipal fulcra is close to the front end of the beam, the effect .(inrespect to the vertical movements of the beam, the body and the wheel)is, substantially the same as if the power mechanism, orp jime motor,were mounted directly on the beam. so asto abut, or having a bearing,against the latter when exerting power to eifect the liftingof the JlOWbody. I prefer to mount common prime power-device for all the units onthe main. frame because of the greater easeof control and thepossibility of employing heavier and more durable parts; but even whenso arranged, it will be seen that the transmitting device of each unithaving nbutments on the beamorranged in the way described does not var?the. relations of the wheel. andbody, substantially, either when thebody is at work in the ground or when it is elevated and insures thatthese two parts shall be held at'proper distances from each other and inproper re I lation to the ground surface when thepl'ow body is in itselevated. position on the Wheels. There is, necessarily, a slight amOuntof slack in the chain, and whether it is carried down directly to,'andbackward from, the beam axis, or is carried around a sheave an inch ortwo distant, the factor of slack is regulated, so that there shall besuflicient' tautness to insure a. quick picking up of thepower'transmitter whenjtis desired to i-nstantly start the plow-'"upwardout of the ground and, at the same time, so that there 1 shall not besuch tautness zis to .preventthe beam from freely moving from 'itsnormal predetermined plane, either down-ward 1.0a"
